A few shots ago I posted a pic where I got the unexpected result of the overlapping lines making a 3D shape so I've been experimenting with some of my different homemade lightblades to see if I can improve on the effect.

 

This one was made with six rotations of my camera on a camera rotation tool of six spins of a light blade on my spinner with the torch set to med power so it fast strobes.

 

Light painting straight out of camera.
